Pull RSS Feeds From Facebook Page

I need help to pull RSS feeds from a facebook page I'm using the following code but it keeps giving me an error :

string url = 
    "https://www.facebook.com/feeds/page.php?id=40796308305&format=rss20";

XmlReaderSettings settings = 
    new XmlReaderSettings
                    {
                         XmlResolver = null,
                         DtdProcessing=DtdProcessing.Parse,

                     }; 
XmlReader reader = XmlReader.Create(url,settings);

SyndicationFeed feed = S开发者_如何学CyndicationFeed.Load(reader);

foreach (var item in feed.Items)
{
    Console.WriteLine(item.Id);
    Console.WriteLine(item.Title.Text);
    Console.WriteLine(item.Summary.Text);

}

if (reader != null) reader.Close();

This code works perfectly with any blog or page rss but with Facebook rss it give an exception with the following message

The element with name 'html' and namespace 'http://www.w3.org/1999/xhtml' is not an allowed feed format.

Thanks

Facebook will return HTML in this instance because it doesn't like the User Agent supplied by XmlReader. Since you can't customize it, you will need a different solution to grab the feed. This should solve your problem:

var req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "GET";
req.UserAgent = "Fiddler";

var rep = req.GetResponse();
var reader = XmlReader.Create(rep.GetResponseStream());

SyndicationFeed feed = SyndicationFeed.Load(reader);

This is strictly a behavior of Facebook, but the proposed change should work equally well for other sites that are okay with your current implementation.

It works when using Gregorys code above if you change the feed format to atom10 instead of rss20. Change the url:

string url = 
"https://www.facebook.com/feeds/page.php?id=40796308305&format=atom10";

In my case also Facebook feed was difficult to consume and then I try with feedburner to burn the feed for my facebook page. Feedburner generated the feed for me in Atom1.0 format. And then I successfully :) consumed this with system.syndication class my code was:

string  Main()
   {
       var url = "http://feeds.feedburner.com/Per.........all";


       Atom10FeedFormatter formatter = new Atom10FeedFormatter();
       using (XmlReader reader = XmlReader.Create(url))
       {
           formatter.ReadFrom(reader);
       }
       var s = "";
       foreach (SyndicationItem item in formatter.Feed.Items)
       {
           s+=String.Format("[{0}][{1}] {2}", item.PublishDate, item.Title.Text, ((TextSyndicationContent)item.Content).Text);
       }

       return s;
   }
